Tancredo-1 is a Brazilian picosatellite, it is a TubeSat which was developed by the students from the school Tancredo Almeida Neves, in Ubatuba (SP), with support for the picosat platform made by Instituto Nacional de Pesquisas Espaciais (INPE), adapting and integration to launch provided by TuPOD[2] from Italian company GAUSS Srl and by Agência Espacial Brasileira (AEB).[3][4][5][6]

Project

The idea was proposed by the math teacher Cândido Oswaldo de Moura, inspired in a reportage about the "TubeSats", kits to build “personal satellites” developed by the company Interorbital Systems, in United States.[4][7] To start the project, the teacher made contact with the Instituto Nacional de Pesquisas Espaciais (INPE), where, later, he was followed by another teacher to receive training and be able to help the students. The material to construct the satellite was paid for by salesclerk of Ubatuba and the launch was possible with help of AEB. The satellite receive the name of “Tancredo-1”, in homenage to school.[4]

Characteristics

The picosatellite is 13 centimeters long and has a mass of 570 grams. The equipment has five plaques in its structure. Solar arrays in the cylinder are responsible for powering the components of Tancredo-1. A space exists inside the satellite what can be used for small scientific experiments in space, in the case of Tancredo-1, two payloads are used: one voice recorder for radio-amateurs, educational payload and one simplified Langmuir probe to study the formation of plasma bubbles in ionosphere made by National Institute for Space Research. The platform tubesat passed by a total re-engineering from the work to Mestrado em Engenharia de Sistemas Espaciais Eng. Auro Tikami from INPE with orientation of Walter Abrahão dos Santos – INPE.[8]

Almost 100 students had a part in the project with the job of welding of pieces and building of electric circuits.[4][7] The experiment after being launched in space, will stay some months in orbit, spinning around the Earth at a distance of 310 kilometers. In this way it will not have the risk of becoming space garbage. The satellite will be attracted by Earth gravity, and then will be burned up in the Earth's atmosphere.[4][7]

The TubeSat started transmission on January 19, 2017 on the frequency of 437.200 MHz in the 70 cm amateur band.
